Damn Jim. I feel for you still on this quest after all this time with little gains. Have you been able to get in touch with any local dealers where you are in Honolulu? I believe Underwood Wally is by you. Also there is Stewart Ono (unclestu) who is also great resource of all things audio. Maybe those guys can help you out with gear. Also is there an audio society or group in HI where you all can gather around and listen to gear periodically? Sometimes that is helpful too. From looking at the current Audiogon listings from 1 to $1100 there isn't much out there that could be an improvement to your current situation.
Best of luck on the search.
